ANSWER: Heliocentric

EXPLANATION: The word that best fits the definition of Galileo is Heliocentric. According to science, Heliocentrism is the astronomical model where the Earth and the planets revolve around the Sun and it is considered to be the center of the solar system. Geocentrism is opposite to Heliocentrism where the Earth is considered to be center of the Solar System.

At a certain temperature, the decomposition of NO2 is second order with a rate constant of 2.85 M-1min-1. If one starts with 1.7

alex41 [277]

Answer: It will take 0.50 minutes for it to decompose to 28.2% of its initial value

Explanation:

Integrated rate law for second order kinetics is given by:

$\frac{1}{a}=kt+\frac{1}{a_0}$

a= concentration left after time t = $\frac{28.2}{100}\times 1.77=0.50M$

k = rate constant = $2.85M^{-1}min^{-1}$

${a_0}$ = initial concentration = 1.77

t= time taken for decomposition

$\frac{1}{0.50}=2.85\times t+\frac{1}{1.77}$

$t=0.50min$

Thus it will take 0.50 minutes for it to decompose to 28.2% of its initial value
